The other massively important resource is Things Fall Apart by Chinua Achebe.
For once Mr.Achebe is a cornerstone of modern African literature. And for all the successes of Black American literature, African literature is a very different depth and reach.
And also Things Fall Apart confronts you not with abstract morals, but it's full of specifics. Customs, phrases traces of which you spot in diaspora. Vibes you recognise elsewhere.
